Description

The invention relates to mechanical engineering and can be used to remove burrs from the docking planes of the sliding bearing shells.

A device for removing burrs from sliding bearing shells and cleaning their outer surface is known, comprising a piece feeding assembly, a deburring mechanism, a cleaning mechanism for the exterior of parts, and a feeding and turning unit for parts. The deburring mechanism includes tools mounted on the motor rollers and designed to remove the burrs from the longitudinal edges of the bearing mating surfaces, and tools mounted on the electric motor rollers and used to remove the burrs from the transverse edges of the bearing surfaces of the bearing shells. Each tool is made in the form of a cylindrical brush with a steel pile.

The known device for deburring the inserts of the sliding bearings and cleaning their outer surface has a complex structure, relatively large size, increased power consumption and less reliability due to the presence of four tools and electric motors used to remove the burrs from the longitudinal and transverse edges of the liners connecting surfaces. bearings.

The aim of the invention is to simplify the design and reduce the power consumption of the device.

Fig. 1 shows a device for deburring sleeves; general form; FIG. 2 is a view A of FIG. one; Fig. 3 shows the device with the parts holder rotated 90 °.

The device for deburring the sleeves of the sliding bearings comprises a frame, a deburring mechanism, a component feeding unit and a component rotating unit. The bed (not shown) is designed for mounting mechanisms and components of the device. It is a box-shaped rectangular welded structure.

The deburring mechanism is designed to remove burrs from the longitudinal and transverse edges of the docking planes of the sliding bearing shells 1. It includes tools 2; mounted on rollers 3 electric motors 4. Tools 2 are made in the form of cylindrical brushes with steel bristles.

The part supply unit serves to move the bearing shells 1 to the tools 2. It includes a slider 5, guides 6, a power cylinder 7 with a rod 8, a holder 9 of parts and a clamp 10. The slider 5 is mounted on the guides 6, which

mounted on the frame, and connected with the rod 8 with the power cylinder 7. In the vertical hole of the slide 5 is installed with the possibility of vertical-translational movement and rotation of the shank 11, on

0 the lower end of which is placed the holder of 9 parts, and on the upper - made annular shoulder 12.

The holder 9 of the parts is designed in the form of a socket into which the insert 1 of the sub5 of the sliding pin enters and is pressed by the clamp TO connected with a power drive (not shown). The holder 9 of the parts is spring-loaded with respect to the slider by the spring 13, which rests on the upper end of the ring shoulder 12, and the lower end of the ring - on the upper plane of the slider 5.

The unit of rotation of parts serves to rotate the bearing shells 1 by 90 ° with the reverse movement of the slide 5 relative to the tools 2 in order to remove the burrs on the transverse edges of the joint planes. It includes a plate 14, a fixed cam 15, a movable cam 16 and a power cylinder 17 with a rod 18.

0 Plate 14 is installed on the frame. A fixed cam 15 with a bevel facing the slider 5 is installed on the bottom in the plane of the slider 5, and on the cylindrical surface of the shank 11 of the slider 5 there is a fuller helical groove 19, which includes a finger 20 mounted on the slider 5. The length of the groove 19 is selected with the possibility turning the holder of 9 parts by 90 ° when the shank 11 interacts with the fixed cam 15 and moves it down after the sleeve of the sliding bearing 1 passes the tools 2.

The movable cam 16 is installed in the transverse groove of the plate 14 with the ability

5 moving it in line with the fixed cam 15, for which it is associated with the rod 18 of the power cylinder 17 mounted on the plate 14. Two bevels are made on the movable cam 16, one of which is

0 matches the bevel of the fixed cam 15, and the other provides for returning the holder of 9 parts to the initial position with the shank 11 when the slide 5 is moved to the initial (right extreme) position.

5 The deburring device with the sliding bearing shells operates as follows.

With the position of the slide 5 in the initial (right extreme) position, the insert 1 of the sliding bearing is any known

the method is loaded into the slot of the holder 9 of the parts and pressed by the clamp 10, for which its power cylinder (not shown) is turned on. The ram 7 and the electric motors 4 of the instruments 2 are turned on. In so doing, the rod 8 moves the slider 5 with the holder 9 parts and its shank 11 to the left. The rotary tools 2 are used to remove the burrs on the longitudinal edges of the joint planes of the bearing shell 1. Upon further movement of the slider 5 to the left, the shank 11 finds the upper end of the fixed cam 15 on the bevel and lowers, compressing the spring 13. At the same time, the shank 11 of the holder 9 parts, interacting with the groove 19 with the finger 20 of the slider 5, turns 90 ° and turns the holder 9 with the insert 1 bearing. At the same time, the power cylinder 17 is turned on, which by the rod 18 moves the movable cam 16 in line with the fixed cam 15.

The power cylinder 7 is switched to reverse and the rod 8 moves the slider 5 with the holder 9 parts and its tail 11 to the right. Burrs are produced at the transverse edges of the docking planes of the bearing shell 1. Upon further movement of the slider 5 to the right, the end of the shank 11 comes off from the copier 16 and under the action of the unclamping spring 13 the shank 11 rises. With

Claims (1)

In this way, the shank 11 of the holder 9 of the parts, interacting with the groove 19 with the finger 20 of the slide 5, rotates 90 ° to its original position and rotates the bearing shell 1, the Slider 5 with the holder 6 of the parts returns to its original position. The power cylinder 17 switches to reverse and the movable cam 16 returns to its initial position by means of the rod 18. The sliding bearing bush 1 moves to unloading. The cycle is repeated. Claims Device for deburring sleeves of sliding bearings, on the base of which there is a deburring mechanism in the form of two tool heads and a component supply unit, characterized in that, in order to simplify the design and reduce the power consumption of the device, the component supply unit is designed as slider mounted on it with the possibility of vertically-translational movement and rotation of the holder parts with a socket and a spring-loaded shank, while the device is equipped with a turning unit de hoists, made in the form of cams with bevels, one of which is fixed on the bed, the axle other is movable, and the shank of the part holder is mounted so as to interact with the fixed cam.
